Just weeks after Japanese officials acknowledged that radioactive water has been seeping into the Pacific from the tsunami-crippled nuclear power plant for more than two years, new revelations of leaks of contaminated water from storage tanks have raised further alarm. The government announced the week of Sept. 1, 2013 that it would contribute 47 billion yen ($470 million) to build an underground “ice wall” around the reactor and turbine buildings and develop an advanced water treatment system.

The Fukushima nuclear power plant in Japan is still leaking
radiation, and at an increasing rate.

Leaks were found in one of the large water tanks used to
hold contaminated water last month, and readings near one of the tanks increased
by about a fifth on Tuesday, according to BBC News.

On Saturday, ground readings showed 1,800 millisieverts. By
Tuesday, the reading had climbed to 2,200 millisieverts.

According
to NBC News, recent readings mean that "hundreds of tons" of contaminated
water are escaping from the area.

The Japanese government has proposed an interesting solution
to control the leaking going forward – building a gigantic frozen wall to
contain it.

The wall, which is based on a similar barrier at the Oak
Ridge National Laboratory in Tennessee, would be built in a 0.9-mile perimeter
around the site. Liquid cooling pipes would be run through the wall every yard,
starting from 100 feet deep. The wall would freeze the ground surrounding the
site, and any water touching the wall, preventing contaminated groundwater from
escaping, NBC
News reports.
